Light curtain control camera based on Internet of Things

Abstract

The invention discloses a light curtain control camera based on the Internet of Things, which relates to the field of the Internet of Things. The light curtain control camera is in communication connection with a light curtain module; the light curtain module comprises a plurality of pairs of infrared geminate transistors which are arranged in parallel, and a light curtain surface formed by each pair of infrared geminate transistors is perpendicular to the ground; the light curtain module is used for detecting the passing of pedestrians and the heights of the pedestrians; the infrared geminatetransistors are divided into lower-section geminate transistors, middle-section geminate transistors and upper-section geminate transistors according to the heights; the lower-section geminate transistors are mainly used for detecting the legs and feet of the pedestrians, the middle-section geminate transistors are mainly used for detecting the abdomens and buttocks of the pedestrians, and the upper-section geminate transistors are mainly used for detecting the shoulders and heads of the pedestrians; the camera comprises a shooting assembly and a main controller; and the camera controls the shooting assembly to perform video recording on the pedestrians in response to the fact that the light curtain module detects passing of the pedestrians. The camera can carry out video monitoring according to whether the light curtain is triggered or not, and electricity is effectively saved.

Description

technical field [0001] The invention relates to the field of intelligent security, in particular to a light curtain control camera based on the Internet of Things. Background technique [0002] With the development of society, the video monitoring requirements for urban safety and road traffic safety are getting higher and higher. According to the actual application requirements, the number of video monitoring points has also increased exponentially. [0003] In the prior art, the camera is always on, but in fact, no one passes by for a long time in the public area of ​​a typical office for camera monitoring. At this time, if the camera is always on, it will cause unnecessary power consumption. [0004] In addition, in the prior art, it is common to perform portrait recognition on pedestrians or use image processing to calculate the height of pedestrians, but there are few studies on the posture of pedestrians. Contents of the invention [0005] In view of some defects in...
